Page instead of Posts

hello folks
this is my 1st topic in this forum, and i hope to find some questions, as i start to use wordpress, I start modding a theme, and to edit it as i want it to be, but i have a problem is the index.php , as I want to have pages instead of posts, so here is the code :

<?php $count = 0;?>
<?php query_posts('showposts=4'); ?>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>

<div class="postindex" id="post-<?php the_ID(); ?>">

	<h2>
		<a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a>
	</h2>
	<div class="entry">
		<?php the_excerpt(__('Lire la Suite »'));?>
	</div>
	<div class="spacer"></div>
	<ul class="post-data">
		<li class="posted">
			<a href="<?php the_permalink() ?>" title="<?php the_title(); ?>"><img src="<?php bloginfo('template_url'); ?>/images/lire+1.gif" alt="Lire la suite" style="height:20px; width:62px;border:0px;float:right"></a>
		</li>
	</ul>
</div>
<?php endwhile; else: ?>
	<p><?php _e('D&eacute;sol&eacute;, pas de postes correspondant &agrave; vos crit&egrave;res.'); ?></p>
<?php endif; ?>

hope someone could help me to fix that, and thanks
